Connecting a UPS

General COM Port Setting

For this configuration step, navigate to the following menu:

Depending on the design and model, the CS141 provides up to three additional COM ports fulfilling different functions. Please note in some cases sub menus will appear to specify functions of devices connected to CS141. To start configuration, go to Devices and press Setup.

Ensure UPS is selected at COM 1:

As a standard, COM1 the setting UPS should be selected. If not, open the drop-down menu and select UPS.

By pressing Apply this selection will be saved and the CS141 will start required services to communicate with the UPS:

Keep in mind by activating this function, a dummy is set first - this is necessary to allow general access to the corresponding sub menus.

The CS141 will display the current starting phase as well as the success of the activation at the upper task bar.

Please note that only a dummy without a function has been started at this point, even if a UPS is apparently connected and in operation:

UPS Pipe-Through Function

COM port 2 on the CS141 is a flexible interface that supports the connection of various devices, such as:

• Sensors

• Modbus devices

• External modems

• UPS signal connections (Pipe-Through)

As part of the UPS configuration, the CS141 offers a Pipe-Through function that enhances UPS signal handling:

With this function, the signal received from the UPS on COM port 1 can be forwarded one-to-one to COM port 2.

This allows administrators to standardize emergency shutdown solutions even when using two physically separated networks:

Each network can be independently managed while still sharing the same UPS infrastructure.

Configuration of the Pipe-Through feature is performed via the Web Manager connected to the UPS. The second Web Manager is set up similarly to the COM1 configuration, but it connects to the COM2 port of the first Web Manager, rather than directly to the UPS.

Note:

When using the pipe-through function, be sure to set the correct COM2 port to Pipe Through. Furthermore, set the same UPS with identical values on both CS141s.

All other settings may differ.
